Ranger Admin install fails with Access Denied error

[#1]

I am seeing the following when it is trying to install Ranger Admin on the Ranger host server:

2016-01-27 08:48:59,962  [I] Database ranger already exists.
2016-01-27 08:48:59,962  [I] ---------- Granting permission to Ranger Admin db user ----------
2016-01-27 08:48:59,962  [I] ---------- Granting privileges TO user 'rangeradmin'@'%' on db 'ranger'----------

2016-01-27 08:49:00,520  [E] Granting privileges to 'rangeradmin' failed on 'ranger'

I have logged onto MySQL on the host machine and granted the following privileges and still the installation throws Access Denied error.

Hi,

We was facing same issue.We tried some resolution

First we tried:

grant all privileges on *.* to 'root'@'hadoop04' identified by 'password';

again we was facing same issue

SQLException : SQL state: 42000 com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Access denied for user 'root'@'hadoop04' to database 'ranger' ErrorCode: 1044
2018-07-03 15:13:50,524  [E] Granting privileges to 'rangeradmin' failed on 'ranger'

we had tried with IP address

grant all privileges on *.* to 'root'@'ip_address_of_rangerhost' identified by 'password';

Which works for me.
